Just got bit by an annoying WP bug: Doubleclicking comment text results in comment reply data-loss

To reproduce:

  1. Go to the Comments page in the WordPress admin (/wp-admin/edit-comments.php)
  2. Click the “Reply” link to respond any visible comment and begin composing your reply
  3. Realize you want to copy a single word out of the original comment, doubleclick the word to select it
  4. Surprisingly, this opens the comment’s “Quick Edit” view
  5. Click “Cancel”
  6. Click “Reply” and notice that whatever you were originally typing above is gone

Ouch.
